Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.

Temp and humidity

DHT11, DHT22/AM2302, and DHT20/AHT20 sensors solve the same broad job, but only some are acceptable substitutes in the same circuit.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
